Here are some example files:
https://drive.google.com/file/d/1ni4YjT ... XEMbG/view
https://drive.google.com/file/d/1hA-ceq ... neCQl/view

The only thing I found about those files is asmodean's exm2lib tool (http://asmodean.reverse.net/pages/exm2lib.html) but it doesn't support that game. I'd be really grateful if someone can help. Thanks in advance.

You need to find the GAME_SEED and key_len of that specific game and edit the exm2lib.exe executable.
There are no quickbms scripts for this format, I already made the decryption work here viewtopic.php?p=22488#p22488 but all the psb parsing has not been done yet.

I'm sorry, could you please elaborate a little more? What are exactly GAME_SEED and key_len? Also, do you have plans on making a quickbms script in the future?

A script maybe, the format is quite boring so it would take some time and desire (that I don't have).

GAME_SEED and key_len are 2 fields necessary for decryption.
For example "Dunamis 15 (XBOX360)" used "4nDSd4sa2v" and 0x54.
For retrieving them you have to analyze the game executable, maybe upload it and if you are lucky someone will check it (I doubt but who knows)
